Hi guys,I been working on this project for some time now on my "free time"...but so far without any success.In the first prototype I have assembled all the peripherals(QSPI, eMMC, SDRAM, some I2C and SPI slaves peripherals and DSI display.).Nothing s...
Hi i m working on H732 timer1 as PWM and its working fine, but when I try to implement DMA on timer1, there is no waveform. I enclosed the DMA code below, as I declare an array of 10 PWM duty cycle values..i suspect it's the Timer1 channel1 stream th...
Hello, I need to make 10 samples via Tim13 and PWM in STM32H7. I implemented the next script, but finally, on the oscilloscope, I saw about 50 samples every 0.1 sec. Do you know, how easily control the number of samples for Timer in stm32? #inc...
HI, For testing and debugging FMC_norflash(MT28EW01aba) with custom h753 board, I used h743i-eval example as it is for read,write,erase, hence, i could read Manufactring code in memory browser, but in live expression i see address is different, so...
I am using STM32 Nucleo-h723zg for a UART serial transmission using UART4 and UART7. I have used UART4 only in my code to test since using both was not working. Still, nothing is showing on my RealTerm serial monitor. I used STM32 Cube IDE. I don't ...
Hello, I have a question to ask regarding a problem with the STM32H7S78-DK card and using FatFS for an SD card, using RTOS.I try to describe the problem in as much detail as possible.I have my own application which includes TouchGFX among other thing...
Hi All, We have recently spun a PCB with a BGA packaged STM32 processor. Unfortunately I am having real problems with the board bring-up. The 3V3 rail is getting clamped to around 1.9V when I have a 100mA current limit on my PSU. A thermal camera has...
Hi Sir , I need your help with some questions about SPWMI:1. STM32Cube_FW_H7_V1.7.0 without Demo project, Could you provide a Demo project of SWPMI STM32H7？2. As RM said，SWPMI can serve only as Master interface, Whether SWPMI can communicate with ...
Heyho,until now I only used STM32 with the LAN8742, in a few weeks I'll get my 2nd custom board, but this time with the "dual" PHY KSZ8863RLL.It's connected via RMII, for setup MDIO (and optionally I2C for the registers not accessible via MDIO).Are t...
Hello everyone! I'm close to validating all my schematics for a PCB project, and I wanted to be sure at 100% that a section is correct.I'm talink about the USB-C section, that connects directly to the STM32H7 microcontroller. It will be used to acces...
