Hello There,I'm looking to migrate from STM32F429ZIT6 to STM32H7A3ZIT6 for a TFT application.I have checked H7 will provide better performance on this.There is one more thing that comes to my mind that H7A3 has better specs than F429. Then why F429 p...
I'm new to the stm32MCU. I am using a Nucleo-U575zi-Q board. I am trying to read ADC values by setting the built-in DAC. I have check my DAC out and it is working fine. My ADC reading is giving me garbage values. I have set HAL_PWREx_EnableVddA() als...
Hi, I have a problem where I cannot debug my code bcs of this error. Anyone know how to solve these problem?btw im using the STM32H750VBT6x for MCU and ST-LINK V2
I am working with a NUCLEO_l452RE, temperature 25°C, 1.8V, and I am measuring current on JP6, so I tried to reproduce: I set up MSI@1Mhz, I got 280uA, much more than 100uA which I was expecting.Later with MSI@24Mhz, I got 3.24 mA, 135uA/MHz, closer t...
Hello,I have a question regarding several timers which are confiugred in PWM input mode (CCR1 is used to measure the PWM period and CCR2 is used to measure the PWM Width). So far when I plug a user signal on the evalution board, I can see the correct...
It is possible to use LPTIM to capture external pulse duration? I am using a SMT32L452 micro-controllerI think it is possible but I can't find hal for:Start lptim to capture external edgecallback functioncorrect setup on cube mx
We are porting code from a STM32L4P5, where we relocate the IRQ VEctor Table with memcpy(g_RamVectorTable, g_pfnVectors, sizeof(g_RamVectorTable)); __HAL_SYSCFG_REMAPMEMORY_SRAM(); // not implemented on STM32L5xxthat works fine, but as commented ...
Hi, i am working on signal wave generation on the STM32L053 Discovery kit. I'd like to see the maximum frequency of signal generation (a sinus with 100 samples using DMA). But the problem is : i cannot reach over ~20kHz, which is not even in the ultr...
Hi guys.I am using STM32G031F6P MCU and i want to use UART TX with DMA in slave mode. But it is not working. RS485 line is always busy. I am using RS485 transceiver (SN65HVD37DR). If i use normal (not DMA) transmit mode, it is working. Code and cubem...
Is it possible to configure 1 or more timers to divide incomming pulses on a pin by a factor (for example 8) and send out the result on another pin?Like this:That way I would not need to implement the counter in software.
