stm32 discovery tft lcd pricelist

In this category we have included a wide range of evaluation boards for the STM32. You will learn and buy here both the official STM32 Discovery microprocessor sets, as well as many other boards and programmers from various manufacturers.

During over a dozen years of uninterrupted development, the STM32 family has had several large product lines, differing in practically all parameters. These include the number and types of peripheral blocks, processor core versions, the availability of graphics coprocessors and floating point processors, as well as memory sizes, and the type and number of housing pins.

The products under the STM32 brand are so good that even the older models for instance – STM32 ARM Cortex-M3 (on which the STM32F1 family was based, i.e. the progenitor of all newer STM32 processors) - continue to enjoy unwavering popularity. Of course, the sensation is mainly due to the latest offers of this well-known manufacturer - for example STM32MP1 (dual-core, powerful processors for embedded systems and containing Cortex-A7 and Cortex-M4 cores). The STM32 Discovery boards are a great starting point for learning about these family of processors, as they offer plenty of possibilities. You can expand them almost freely. They are equipped with a lot of memory, thanks to which the work is ultra-fast. The undoubted advantage is that we get a very high-class PCB for really little money!

STMicroelectronics has been supporting its recipients for many years, providing both constantly developed libraries and programming tools. Together with individual boards, users receive a very extensive documentation or a wide range of hardware tools. STM32 Discovery evaluation boards belong to the latter group of products.

STM32 Discovery is a set that allows you to quickly learn about the capabilities of ARM core processors. It cannot be denied that these boards, due to a well-thought-out design, allow you the complete configuration of all GPIO lines and the method of core clocking. Discovery microcontrollers are also perfect for rapid prototyping and firmware development without the use of the target PCB of the designed device.

The simplest STM32 Discovery modules contain only the most necessary peripheral elements such as LEDs, buttons, GPIO connectors. The more advanced versions of the STM32 include a number of communication connectors (Ethernet, camera connectors), as well as high-quality LCD touch screens and additional memory banks. Along with offering the highest quality parameters at a reasonable price, the STM32 brand begins to enter the podium of the best microprocessor suppliers in the world (if it is not already there!).

In this category, we have collected the most attractive tiles from the wide range of STMicroelectronics. You will find here both the most popular STM32 microprocessors models and even the rarest, but still attractive ones.

Cheaper STM32 Discovery sets with STM32F051, STM32L100 or STM32F072 processors are perfect for preparing simpler projects, using processors with ARM Cortex-M3 or ARM Cortex-M0 cores. For medium-sized projects, it is worth considering the use of efficient processors from the STM32F429 family - in our offer you will find the STM32F429I-DISC1 board with a 2.4-inch LCD touch display.

It is worth knowing that if you plan to build a project with advanced graphics support or internet connectivity, be sure to check out the STM32F746 or STM32F769 processor kits available in our Botland store. STM32 / Arduino / Raspberry Pi – these are all one of the most popular products in our store. The individual components are compatible with each other in most cases! Enjoy your shopping in Botland!

Description:Here"s a very cool TFT LCD display with 128 x 160 resolution and 18-bit color depth. The most unique feature of the screen is the ability to read back the display memory across the bi-directional data lines. This solves a big problem with most displays - the need for a lot of memory to create effects like transparency or overlapping windows. This is an ideal component to include in your next custom project to advance your embedded hardware/software skills.

The reason that we"re reselling this part rather than using it on a new product is because of a misunderstanding about the interface details. It uses a 3-wire SPI interface with 9-bit transfers. The first bit is used to indicate if the following byte is data or a command. While 9-bit transfers are supported by many modern microcontrollers (like the K66 or STM32 families), making that work with vanilla Arduino is unlikely to happen any time soon. Since SparkFun products need out-of-the-box support for Arduino the interface had to be restricted to bit-banging - just too slow for a display with this resolution!

Ahh yeah look at that! If you look closely, top right of the LCD, that’s obviously a flex connector for a resistive touch overlay (4 contacts running to the 4 sides of the LCD overlay).

Agreed! I will be picking one up. I’ve been happy developing for the stm32f4discovery (and other stm32 chips) with gcc, openocd and gdb. It is all free.

The STM32F4 cores are pretty well supported by libopencm3 and Code Sourcery and summon-arm-toolchain both build working toolchains and openOCD supports the stlink natively now.

A fair number of inexpensive baseboards/motherboards/accessories have also appeared for earlier versions. I hope Olimex puts out a couple nice STM32F429/427 boards.

I can see there is only a STLINK usb connector on board, so there is even no FS to expect. beside HS, I suppose does mean High Speed (480mbps). but HS anyway needs a separate physical layer USB chip for addition to STM32F4 chip and most likely this is chip is not present on this board anyway, because this is STM32F4+LCD+SDRAM demoboard and there is no need for USB at all.

The data brief bullet-points “USB OTG with micro-AB connector”. Looks like the micro-usb is on the underside, sticking out at the bottom of the photo. With matching T/H mounting tabs on the topside, labelled USB USER. But like you said, the STM32F4 requires an external PHY for HS, and it seems unlikely they’d include one on this board.

I think Farnell’s 21€ will be accurate, as ST’s suggested USD price is $24. The placeholders for the STM32F429I-DISCO on element14 (a division of Farnell) and mouser show $42, which I think predates the later ST announcement. I think the ST announced $24 will hold, and the distributor prices will match that, as they have in the past.

I wouldn’t expect TI to hack profits from their calculator range, and HP have always been expensive, but ST could easily change their format to calculator-friendly. Clamshell design, LCD & battery in top half, CPU & keypad in bottom half, expansion pins to left / right of keypad makes a self contained unit.

HP Palm – Love the idea, hate the baguette (french bread loaf) layout. If I could get custom key covers, and surface-mount key switches, I’d be designing my own low-profile keypad to go with an LCD module. Top side keypad, bottom side CPU / RAM / USB / LCD driver / power regulation / expansion port.

Great find, thanks! Man, could they have buried the details on that guy any farther down into the document? I can’t help but feel like a quick pointer in the LCD section to “oh by the way there’s a touch screen, here’s how to talk to it” would have been a good idea.

It’s certainly useable in any other project where you have an onboard LCD controller. Especially any other project that happens to use a STM32F4. What difference would it have made if it had an external controller? Surely it’d have been on the same PCB. Were you hoping for a removeable SPI-interfaced module?

Look in the UM1670 user manual, paragraph 4.8: the tft includes an ILI9341 controller. The ILI9341 has it’s own graphics ram inside, it is not mapped into the STM32 address space. It is connected to the STM32 via a parallel bus. The ILI9341 and similar controllers are common on cheap chinese tfts. So it is no problem to source similar tfts for your final product after developing on the discovery board.

UM1670 in paragraph 4.8 also says that “The TFT LCD is a 2.41″ display of 262 K colors. Its definition is QVGA (240 x 320 dots) and is directly driven by the STM32F429ZIT6 using the RGB protocol”. ILI9341 has multiple modes of operation including direct RGB/HSYNC/VSYNC mode which bypasses internal GRAM. I don’t have the board yet but I assume display buffer is located in external SDRAM which is also on the board. The whole point of this kit is to show TFT and SDRAM interface in new STM32F4x9.

I’ve checked this discovery board firmware available from ST’s site (“STM32F429 discovery firmware package UM1662” number: STSW-STM32138, btw. finding it is a bit difficult – ST’s site is terrible):

They are using FreeRTOS, FatFs, STemWinLibrary which is ST’s version of Segger’s emWin graphic library and STM32F4xx_StdPeriph_Driver v1.2.1 which includes F429/439 support (FMC, LTDC and DMA2D added).

Check again martin. Those lines have pullups to vdd and are connected to cpu pins. I have this board for some time and I can confirm that lcd is driven by lcd controller from cpu and frame buffer is in external dram which is also on the board.
