I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...
I'm a bit lost by this one. I can write to the flash but cannot erase a sector. I can erase sectors with the ST-Link Utility. The result codes at every step indicate success, but the flash is not actually erased. I am using the Standard Peripheral Li...
I am using STM32L431RBT6 consuming 2.63mA of current. How can I further reduce the current consumption ?. I am using MSI at 8 Mhz , and peripherals used are SPI1, SPI2, UART and I2C.
I'm using STM32F429 and trying to use HAL library to communicate to SPI slave via DMA channel. I'd like to ask how is resolved problem with for example sending data to SPI via DMA? Is there any kind of synchronization between SPI and DMA to disallow...
Hello,is there any way to achieve this timer OPM behavior?Arm timer ->Output is inactiveStart timer-> Output gets avtiveCompare register triggers -> Output gets inactiveARR triggers: Timer stops _and_ Output stays inactiveAt the moment, I force the O...
Hi,I'm using the STM32F091 microcontroller on a custom made PCB, i'm reading two switch buttons, both have the following configuration (image below), the SENS_P signal go directly to PA10 of the microcontroller which is configured with EXTI triggered...
Hello all,I am using the h743i eval board and trying to store a large array on the sdram.The problem I am running into is no matter what address I write to, when I read back a value I receive the last value written. I think this may be an issue with ...
Hi,I was wondering if someone can point me to a link where I can download the firmware detailed in the application Note: AN3322Watt-hour meter based on the STM32F101 microcontrollerThanks in advance.
