Sorry, my first time programming an STM32. I have a bunch of data I need to store for a few hours, and the thought was to store it in Flash since there's a lot more of it (512k vs. 128k for regular RAM) but it looks to be pretty daunting. I've been ...
Hello All,I designed and built a bare metal board with an STM32H723ZGT6 and it runs fine.I have blinking LED's, timer / interrupts running, HSE and LSE etc.I have been trying to figure out why if I toggle the power supply the device will not boot up ...
Hi,I am a beginner in STM32 programming. I chose purely register based programming approach without using HAL as I find it a bit harder and slower but more contributing to the overall system performance in the long term code writing skills. This time...
Two devices A & B are communicating on UART. A sends data stream to B. B sends one byte data back to A to acknowldge that data has been received. I want to implement if A doesn't receive acknowledgement from B then it display Error message on LCD.Ple...
Hello,we have a validated project based on the stm32l072rb (FLASH 128KB) microcontroller and in stop mode the entire system consumes 3.5uA.We have updated to the stm32l072rz (FLASH 192KB) and the stop mode current raised to 23uA. In standby mode both...
I am trying to establsih communication between a NUCLEO G474RE and a NUCLEO H7A3ZI-Q thorugh FDCAN. I have successfully accomplished FDCAN communication for both the boards individually using Normal mode as these boards have multiple FDCAN peripheral...
Hi,i was hoping, that the Link-V3 would just work, after i used nucleo boards already. But i was dissapointed. I use the GDB server, and it says:ST-Link enumeration failedError in initializing ST-LINK device.Reason: ST-LINK DLL error.I just checked a...
Hi everyone, I'm deep into developing a project that is not only a passion but also a venture I'm financially invested in. I recently ordered a small batch of 50 PCBAs equipped with STM32L476RET6 microcontrollers from a well-known Chinese manufacture...
Hi all,I am using an stm32wb55 neucleo board for a wearable based project. I am using ADC1-IN1 to read the adc raw value from MCU pin PC0 of wb55 board. A voltage divider circuit was connected to scale down the BAT voltage from (4.2-3.7) to (1.8-1.5...
