Hello,I have a question regarding the bootloader of the STM32C0 (especially the TSSOP 20 version STM32C031F6Px).According to the datasheet and the reference manual, the bootloader can communicate via UART1 and I2C1.The pins it is using are PA9&PA10. ...
After the cube ide and programmer updated, the debugger broke and this is the message I would get:make: *** No rule to make target 'ENGC 371\project1\file\STM32F429ZITX_FLASH.ld', needed by 'project1.elf'. Stop. what would be the best take? i am usin...
Hello,we have an electronic with two possible µC as footprint on the PCB.STM32L071CZSTM32L071KZInside the layout it was necessary to route two signals to different GPIOs, thereforewe have a difference in the configuration.We want to avoid a #define t...
I am using STM32CubeIDE version 1.14.1 on a WIN10 machine.The following C code asm("VMUL.F32 s0, s0, s0"); volatile float xyz = 3.1415; xyz = xyz * 2.3; disassembles to the following: 79 asm("VMUL.F32 s0, s0, s0"); 08000df0: vmul.f32 ...
Hello,I am using NUCLEO-F756ZG. My application is ADC related. I am measuring an analog signal at high sampling rate. Recently, I had a discussion with my team and had an interesting proposal. Our target signal is pretty much guranteed to be within 0...
On STM32G474, I have a loop where I read ADC values, process them, and write the result to DAC.I am using the dual ADC mode and reading ADC12_COMMON->CDR . I do not care if I read the previous conversion result, in this case, is there a reason to che...
Hello, I am having a confusion in understanding the Clock Frequencies for STM32L452RE. In the Datasheet its mentioned that "Several prescalers permit to configure the AHB frequency, the high speed APB (APB2) andthe low speed APB (APB1) domains" It al...
I'm working on migrating a design from STM32F405 series to STM32G473 series, both LQFP100 package, both use FSMC for access to external SRAM (in multiplexed mode; I have separate address latches clocked from FMC_NADV capturing A0..A15 from D0..D15.) ...
In my project, my MCU (F411) uses I2C HAL API routinely to read from a sensor device.When some event happens, my interrupt handler will use I2C API to read from different register from that device; so my question is:Is HAL API thread safe? Although I...
I've been having issues with getting an SD card working on an STM32L4R5ZI Nucleo board when using essentially the same code (with minor tweaks) without issues on the STM32WB55 Nucleo board. I've been going through the code of both to determine where...
