ILI9341 LCD on STM32F4 108

Library 18- ILI9341 with LTDC on STM32F429 Discovery

It’s been a while when I first got ILI9341 lcd working on discovery, but without LTDC driver. Yesterday I decided to make a new library. With LTDC, you can actually display movies, because it uses parallel communication and support 2 layers simultaneously what gives you a high refresh rate. I used my old ILI9341 library and just add/modify some things to get LTDC to work. LTDC also supports 2 layers, so this means that while one layer is displayed, other layer...

All STM32F4 libraries 128

All STM32F4 libraries

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...

Library 14- Working with SDRAM on STM32F429 Discovery 53

Library 14- Working with SDRAM on STM32F429 Discovery

STM32F429 Discovery board has external 64Mbits or 8MBytes SDRAM chip ISSI IS42S16400. STM32F429 has a FMC (Flexible Memory Control) peripheral to driving external SDRAM with hardware. FMC hardware is able to store up to 32bits variables at same time. External SDRAM capatibilities Variable size Max value Max address Max variables stored 8bit 0xFF 0x7FFFFF 8388608 16bit 0xFFFF 0x7FFFFE 4194304 32bit 0xFFFFFFFF 0x7FFFFC 2097152 Note: This library does not work on STM32F4 Discovery, because this MCU does not have FMC peripheral....

CMSIS - Cortex Microcontroller Software Interface Standard 198

STM32F4/29 Discovery with CMSIS library in Keil uVision

From this moment, I will use in my projects Keil uVision. It’s true, that Coocox is free, but it has some bugs, which are great fixed in Keil. Keil has some limitations for free (32KB flash support, no optimization) version, but for our examples and libraries, it is just fine. For updates, look at my Github projects repository, where are all projects and libraries. There is no included my libraries in bottom project, you have to download it manually from Github. All...
