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.
I'm developing a new design with a STM32G0B1x uC. Therefore, I will use a 12MHz or 8Mhz external (HSE) crystal quartz from Abracon. I just read through the AN2867 and did some calculations. Now I'm at the point where I would need to measure the drive...
I have a FT231XS on my board and a STML451. I would like to communicate over Uart to STM. So i need the FT231XS as USB to UART converter. My software works with NUCLEOL425RE, so when i send some strings over a Serial Port i can receive it immediately...
Hi, I've been looking at timer examples for days and can't seem to find what I need. If I find something, then the interrupt routine isn't listed, for example.I have a precise 2.5Mhz signal that I want to count 25,000 times and then overflow. I don...
