I use the Vbat pin to measure a lithium battery (3.6V) at a STM32L471 (Vcc=1.8V Vdda=3V).However my measurements are off by ~0.15V even though I confirmed the physical signals.Do I have to calibrate the ADC somehow for this to work properly?Expected ...
Hey Guys,I have designed a custom board with the STM32F429ZIT6 which I programm with the STLink debugger together with TrueStudio. So far everything seems to work except that when I don't use a debugging session I have to manually make a reset on NRS...
Hello,both datasheets and rm0394 rev 4 talk about " Manage single-ended or differential inputs" and Figure 39. : ADC block diagram show ADC_INP[16:1] and ADC_INN[16:1] . However Pinout tables in chapter 4 : Pinouts and pin description only shows ADC...
We have tried to set an rtc alarm interruption but it does not work. We can see in debuuger in the system viewer that the alarm has been configured. But when it comes to see the alarm interruption we see that it does not occur.See bellow the code fo...
Hello. I want to use STM32L471ZGT to write a rare signal to flash. All the rest of the time it should consume as little as possible. I config RTC for alarm (and then try wakeup), all working perfectly if ambient temperatures -10C and above. But proce...
Im using a STM32L152RDT6 in my design and a regulator TPS78326 which does the power supply to the STM. If waking up from STANDBY, the load transient response causes a drop of Vin. In this case 2.6V to 2.4V. The STM is supposed to work down to 1.8V, s...
I am doing a project using STM32H753 controller. When I flash USB HS MSC example code and transfer files , speed is very slow. It seems no difference between FS and HS modes. A large compressed files do not get transferred. Please help.
I am having problem with writing program to internal flash memory. How to read from flash and write to flash? How to compare flash contents with uint8_t array contents? How to write uint8_t array contents to flash memory ? Please help
Solved: The problem was an improper reading, the BKSRAM-clock was not initialized when reading back the report. Updating with "correct" code for posterity.I'm writing a (better) hard-fault handler for my STM32f207zg and want to do the following:Have ...
