Hi,We have a question about a system design we would like to implement for our product.We are working with the STMF32F723 MCU and are developing our own HW. We need 216MByte of RAM for our application and would like to implement it with the functiona...
HiI have a question for my colleagues who use FMC to communicate with LCD. I am using CoreH7XXI with 743. The display does not respond to the data I send to it. I used Core4X9I with 429 before and everything worked. My question is whether I need to s...
I should combine STM32F479 with PROFIBUS-DP ASIC SCP4-2 The chip is aged. And requires delay of at least 30ns (by 3v3) between address and cs. Our previous design was based on SAM4S and their CPUs are offerring register to program such delays. In STM...
Hi.I want to configure a SDRAM in a stm32h743iit6 custom board.but question is where can I can set the clock of FMC, from below section? if I set it on 240MHz then the SDCLK Pin supply SDARAM with 240MHz or half of it? or should set with another para...
Hi,I have inherited a project that utilizes Nuttx RTOS. This project is to change out the LCD display due to EoL. We are changing from Renesas R61580 Driver to Ilitek ILI9341. The existing driver is hooked up via 16-bit MCU command via the FSMC, with...
Hi,I'm currently trying to understand the recommended MPU config (when settings up an 8 bit LCD connected via the FMC on an STM32H742. Everything is currently working, but I haven't been able to wrap my head around why configuring the MPU regions wit...
I'm trying to write to a single register of a LCD controller using the 16 Bit FMC peripheral in SRAM mode.[update)My assumption at the moment is that the controller writes 64 bits even the command STRH should only write a half word (16 bits).When wri...
Using STM32H743IGKx.Tools: LinuxSTM32CubeIDEVersion: 1.12.1Build: 16088_20230420_1057 (UTC)STMCubeMXVersion: 6.8.1-RC4Build: 20230419-1431 (UTC)When setting up the SDRAM configuration in MX, I end up with a couple of signals that look like they are n...
HiDoes the STM32F411ceu6 include an FSMC controller?Thanks
I've been trying to run the fmc and lcd over an 8-bit data line for a few days. Yesterday I managed to read the ids of the lcd correctly, but because I messed up the timing settings of the fmc (timing settings were working randomly), I can't get any ...
