I'm trying to drive a display controller and have found it trickier than I anticipated, and I hope you can kindly help. My microcontroller is the STM32U545. My display controller is the UltraChip UC1628c_A, as part of a custom 160x160 monochrome LCD....
Hi allI'm pretty sure this was already a topic, but i haven't found a solution yet. Since i'm a beginner i definitely need some help here.I'm sending UDP data with LWIP and FreeRTOS. It works, but after some (random) time the code gets stuck at co...
Hello,I’m developing a USB composite device on STM32 that combines RNDIS and CDC interfaces.The device works perfectly the first time it’s connected to a Windows 10 PC — both RNDIS and CDC functions operate normally.However, after I reset the MCU or ...
I've just brought the stm32h573i-dk dev board and what to become familiar with Threadx and USBx. I have a uni project coming up that I would like to use the board as a msc device but struggling to get the board to enumerate with the PC. I have tried ...
Hi I'm trying to use an LP TIM to generate an interrupt after a time interval on an STM32U073CCT6. The interrupt will wake the processor from STOPMODE2.I haven't found any examples, and the STM32CUBE MX doesn't have a software-triggered single-shot o...
Hi everyone,I have a STM32H573I-DK and try to port FreeRTOS without TrustZone to this board by CubeMX but suffered from a problem.I installed the X-CUBE-FREERTOS, set TIM17 for HAL Tick and SysTick for FreeRTOS.It will block (or crash?) in vStartFirs...
I think it doesn't have an impact and you just get extra pins (e.g. extra SPI controllers becoming accessible) if going say 100 to 176. But it's not clear...IOW, will existing code run exactly as before? Isn't the silicon identical and they merely bo...
Hi, I am using STM32G474RE. I try to read out LTC2440 with the SPI interface. I have configured the LTC2440 as SPI master (In its datasheet the mode of operation is specified as Internal SCK, 2-Wire I/O, Continuous Conversion). The LTC2440 provides a...
hi, I'm using stm32h745 dual core MCU, in this i want to know about the caches.these I cache and D cache are default enable are it will enable from IOC configuration of M7 core.if not enabled from IOC still these caches will work automatically?due to...
Hello community,I am new to stm32, and I need to read the temperature from the internal sensor of a stm32g4vet6.I am at the point where I have read many things and have discovered that not all stm32's internal temperature sensors must be used the sam...
