3.3V power supply for NucleoF103

2024-04-03
Hello,I need to power the NucleoF103 development board using an external 3.3V power supply. I have read in the NucleoF103 manual that this is possible by removing SB2 (to disconnect the voltage regulator output) and SB12 (to disconnect NRST). I also ...

STM32F334R8T6 can not read memory

2018-04-12
Posted on April 12, 2018 at 10:08I have designed a board with STM32F334R8T6. The STM32 pins are configured as in the attached file (I do not think there is a problem here since I have already used the same configuration without problems). The microc...

UART IT

2017-12-04
Posted on December 04, 2017 at 18:18I am using Nucleo F334 and STM32 Workbench as IDE.I need to build a bridge between UART2 and UART3. It should work this way: data are continously acquired on USART3_RX by interrupt and transmitted on USART2_TX.I a...

ADC with DMA in circular mode

2017-09-28
Posted on September 28, 2017 at 10:44I am using the Nucleo F334 development board. I was trying to read the ADC values of PB0 and PB1 (ADC1 CH11 and CH12) using DMA in circular mode. The code should transfer the two 16 bit values of ADC to the varia...
