Is USART1 on APB1 (AN5593, tab.17) or APB2 (DS, RM, CubeMX) and USART2 on APB1 (DS, RM, CubeMX) or APB2 (AN5593, tab.17)? Guess, there is an issue in an5593-how-to-use-the-gpdma-for-stm32u5-series-microcontrollers-stmicroelectronics Rv.4 , isn‘t it?
Hello forum,I need some hardware help to modify my PCB, which was developed by other people.I use STM32F103. I have one "Master"-Board and several "Slave"-Boards (up to 20) with same controller.Because of current saving reasons I need to set the cont...
Hi! I am using an STM32F103C8T6 mikrocontroller and i program with makefile and VsCode. I use the CAN on it and i need to work with STDID and a EXTID. On the bus there is dozens of standart CAN messages and sometime exteneded messages. From the stand...
Hello everyone,i would like to know if it would be possible to write data on the STLINK mass storage device from the firmware application. This would be really awesome for debugging, logging, testing, etc.I am only aware of dragAndDrop programming fe...
The total power consumption by STM32H735VGH at full speed interleaved mode differential adc configuration?
Hello forum and devs!Have one simple question: datasheet of STM32F407ZGT (STM32F40x series) and Cube MX says me, that this MCU doesn't contain USART6_CTS pin, but contain two USART6_CK pins. Is it mistake, and where is USART6_CTS pin?Official datashe...
We have received STMICROELECTRONICS SPC58EG80E5QEC0X, the Terminal Plating is Nickel/Palladium/Gold (Ni/Pd/Au), we see that the terminals look copper finish
Hi! I wonder if the P-divider for the PLL1 on the STM32H743 is allowed to be 1.The reference manual (rev. 8 ) states in figure 47 (section 8.5.5) that only values from 2, 4, ... to 128 are allowed. In the register description (section 8.7.13) however...
Good morning, I have some problems with interrupt priority on the STM32F429.I set up a serial communication on UART1 with this priority// USARTNVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;N...
Hi all,I tried to configure timer 14 to generate interrupt every 500 ms . i am toggling an GPIO to measure delay .when put a breakpoint interrupt gets triggered but unable to see waveform in logic analyser of GPIO toggling with delay .My clock freque...
