Resolved! STM32G050C8T6 ADC_IN11: inconsistency in the datasheet?
Hello,According to the datasheet PB7 can be used as ADC_IN11.Is this an error in datasheet? ADC_IN11 is already used by PB10 and cubeMX doesn't seem to allow me to use PB7 or to remap this pin. How can I use ADC_IN11 on pin PB7 as mentioned in datas...
STM32H747I JPEG DecodeDMA
Hi all,I´m new to STM32 and just recently bought an STM32H747I-DISCO. I needed one with a touch screen for a project. I was going thru the examples and got the LCD DSI SingleBuffer to work but was having problems with the JPEGDecodeFromFLASH DMA. I u...
STM32L4A6 reading OK but writing failed "error erase memory"
Hi everyone,I'm getting stucked with a programming issue.I try to load a HEX file into a STM32L4A6 chip on a BMS board.I've checked the wiring of the st-link/v2 programmer and everything is OK.The chip can be read from the CUBE software but when i wa...
IEC60335 SelfTestLib
In our legacy STM32f103 project a ST library named "Self Test Library" is used. It has version 1.0, dated 10/01/2007. That library is certified according to IEC60335. I found it in an archive named IEC60335.zip, but I have no idea if that's the origi...
Resolved! STM32H723 Internal Temperature Measurement vs. Ambient
All:Setup - STM32H723 with VREFP = 3.00 VI have connected internal temperature to ADC3, and I am able to display degrees C on "Live Expressions". With VREFP set to 3.00 V, I am seeing lower readings than ambient. Using __HAL_ADC_CALC_TEMPERATURE( ), ...
stm32L5 write flash problem
Hi. I am testing flash read and write operations.In the main function, when I write 1 to address 0x08006000, I can correctly read back 1. However, when using FreeRTOS and performing the same operation within a task, I read back garbled values (such ...
Resolved! STM32L562 hard fault in SPI_WaitFifoStateUntilTimeout
I am using MX25 NOR flash memory 256Mbit (https://www.mxic.com.tw/en-us/products/NOR-Flash/Serial-NOR-Flash/Pages/spec.aspx?p=MX25L25645G&m=Serial%20NOR%20Flash&n=PM2075#Technical-Documents) and I am mounting a littleFS file system on it. The memory ...
Resolved! STM32G0B and USB Custom HID
Hello guys!I'm using USB custom HID on STM32G0B for an application alike the mouse demo on "STM32G0C1E-EV" HAL package. But instead a button sending the Report, a PC software sends a 64 bytes Report to get another 64 bytes as answer.In fact, this sam...
Resolved! TIM1 in Encoder Mode but TIM1->CNT does not change
Hi, I'm interested in using Timer 1 on my STM32F439ZI to decode the quadrature signal from an encoder but TIM1->CNT doesn't appear to change. I'm not sure what is missing, the TIM1 config looks like: static void MX_TIM1_Init(void) { /* USER CODE BE...
