I'm using the STM32L031K6 chip. I have a 100HZ signal connected to PA0 (Timer2 ch1) and PB0 (Timer2 ch 3). I think I've setup everything correctly using the CubeMX.The problem I'm finding is the interrupt only fires for the positive going edge on T...
I am running the embedded web server on the STM32F7 and I changed the linked image that is displayed on the MCU. It compiles, but doesn't display. After investigating, a buffer size error is being thrown and consequently the main code gets stuck in...
My board is Nucleo F401RE. This is the first time I've ever been doing this.I am using a pointer to the main registry of ETM, its address I read it on the datasheet.My problem is that wanting to change the bits of this log I do not change it the corr...
These solder bridges are in fact by default OFF, as these signals would collide with the LCD (as text elsewhere in the same manual points out).May I at this point ask again for a table with describing connection of all pins on the target STM32L476, a...
HiMy stm32l433cc circuit has two different LDO, one for Vdd and another for Vdda. Can you tell me please can i run my controller without Vdda power? I need to turn on/off analog power when i need it. Is it possible on stm32l433cc?
Hello,I'm trying to get data from an external ADC (18bits) with an STM32l476RG nucleo board. There is a lot of overhead and I will improve it later but even the frequency clock is not fast enough. I don't understand why but the maximum clock frequenc...
Hi guys! In my project Im reading samples with the adc at 48Khz using timer interrupts and adcConvCallbacks, load them in a buffer of 256 samples and when the buffer is full I send it via i2s to the DAC . Im using two buffers, when the bufferA is ful...
Hi,With helping of CubeMX I measure voltage on battery (ADC channel 0) using ADC in DMA mode. I also measure internal refference because my VDDA is not know in advance.Once these 2 values are measured I need to convert the RAW data to mVolts.I use da...
Hello,I am a beginner to Nucleo-64 board programming and I am trying to work on USART communication of it. I am using NUCLEO-L476RG board and STM32CubeLL library for configuring USART and starting communication with it. Programming Scenario:I have co...
Posted on December 08, 2016 at 19:01 So I finally got my IL9325 TFT display running via FMC but it is running much slower than I expected. The SPI based displays on arduinos seem to be performing better than this parallel setup. I measured my data ...
