All other GPIOS work but these two do not. They get the same voltage as the rest (0 and 3.2V). All pins Vdd and Vss I have them well except pin 97 VDD_USB that by mistake I have connected to GND.I have attached the project with which I have been test...
Hi all, I have a problem to show float numbers via sprintf, I'm working with STM32F334I did a program to print via serial the voltage read from ADC, in float format like %4.2f, the problem is that the first time the sprintf generate a valid string wi...
Hi，Masterplatform:stm32f030C8TxI saw the data sheet as described below:My schematic is as follows:These LED lights can be lit at the same time, the program can also run normally, but their current sum has exceeded 3ma. Although it violates the descri...
I'm working over STM32f334, i config cubeMx to use TIM6 o TIM7 to generate interrupt every 20ms, but interrupt is not fired.I'm finding a official examples to use HAL to config TIM as internal interupt.Any idea? any ink?ThanksJordi
Hi there,I am using the STM32F373CC in LQFP48 package on my own application (not a nucleo or discovery board) with all supplies and references connected to 3.3V and decoupled as suggested by ST.The microcontroller is running as expected, I/Os are ope...
once i programmed my MCU then only one option ERASSE FULL CHIP and reprogrammed it How can i do this?I am using ST-LINK V2 for programming and IDE KEIL & STLINK UTILITY.
helloConsidering purchasing the J-Link PRO SEGGER to aid my developmentI like the idea that it runs from Ethernet and has all the advantages of using EthernetAlso like these feature of deeper and more advanced debugging and trace etc.Can any one plea...
Hi,I am using STM32L431 controller, I would like to know whether BOR is enabled by default or we have to write code to enable the BOR. I Assume that, by default it is enabled for threshold voltage 1.7V. Please share your input on this. Thank you in ...
After updating CubeMx from 4.27 to 5.0.0 I ran into trouble regarding the newly created module syscall.c:compiler error (had to switch the C++ dialect settings from "-std=c++0x" to "-std=gnu11" to fix it)but firmware is now not running - it stucks in...
