In DS12923 (Rev 1), it is stated that VOS0 is only available with LDO, but it is not clear if LDO-Only mode is required or SMPS-LDO cascaded mode is okay.First,3.5.3 Voltage regulator (SMPS step-down converter and LDO) says• Run mode (VOS0 to VOS3)– ...
I am using STM32F427 controller for my application development. I need CAN to work at 1Mbps. The Bit Timing parameters configured are BPR - 1, TSEG1 - 6, TSEG2 - 6 and SJW - 3. But these values are not working, when trying to capture the CAN message ...
Status from reads: WUTE is enabled, WUT shows what I set, RTC is enabled, and the WUTF flag is correctly being set every so often (and manually being cleared during GPIO interrupts I'm troubleshooting with).What's not happening: The EXTI interrupt is...
Hello,I'm using the STM32L475RC as a SMBUS/PMBUS Client and generated the Code with CubeMX.As smbus/pmbus stack I use the X-CUBE-SMBUS Expansion Package (AN4502).I've read and studied the examples that come with the package and tried to configure the...
Hi,I enabled the DAC and a GPIO Pin as analog. But whatever value I provide, the GPIO Pin of the DAC never reaches a value above 20mV. DAC config:static void MX_DAC1_Init(void) { /* USER CODE BEGIN DAC1_Init 0 */ /* USER CODE END DAC1_Init 0 ...
A lot of documents report that is possible to use DFSDM to encode and decode Manchester.Unfortunately i'm not able to find any example code.Any suggestion?
Hello everyone!Problem 1:I bought 8 STM32 Blue Pill cards.I can't program these cards.The problem occurs on all boards.When I set the BOOT jumper 0 to 1 and press the reset button the LED connected to the PC13 pin always flashes.I have already progra...
I wrote I2S Loop back test program. I2S2 as Master Transfer mode and I2S3 as Slave Receive mode. (Proto for ADC in and DAC out.)It works OK when 16bit in 16bit frame. However, in 24 bit in 32bit frame, DMA pointer etc. are corrupted.With step-by-ste...
Hello all,I want to disable the timer interrupt in the IRQ Handler and then enable again in the main loop. However the interrupt is triggered nearly immediately after I re-enable the interrupt (setting the UIE bit). I attached my code below. If I dis...
