I have a photo interrupter attached to an interrupt port powered by the 3.3. volt supply.Every now and then, there is a burst of activity on the 3,3 volt line which cause havoc on the interrupt line.img_0933 shows the output of the photo interrupter ...
Hi thereI am trying to configure a GPS receiver chip (MAX2769C) with an stm32f446re MCU using SPI in half duplex master mode. The chip is expecting a 32 bit word (4 bits address and 28 bits data). This is on page 21 of the attached datasheet. My firs...
In order to wakeup the microcontroller from standby mode, is it necessary for the wakeup pin to generate a rising/falling edge or it should only have logic high/low level? In the datasheet it says rising/falling edge, however inside the HAL functions...
I'm currently receiving image data from TTL camera and sending it via Bluetooth. Baud rates for camera (VC0703) and Bluetooth module (HC-06) are 115200 and 230400, respectively. I'm defining camera rx buffer size and Bluetooth tx buffer size as 60000...
1) Index contains SYSCFG_MEMRMP but there's no such register in 'F3032) in 5 figures' caption, AUTODLY is mentioned, but there's no such bit, the correct name is AUTDLY (without "O", bit 14 of ADCx_CFGR).JW
Below is my benchmarking of multply-accumulate performance on contiguous memory blocks on the STM32F7508-DK board for three different types of memory (on-chip SRAM, external SDRAM managed by the FMC, and QSPI-connected NOR flash):The horizontal axes ...
I have a STM32G030K6T. Right now I can wake up from standby with either wake up pin falling or rising edge. How can I use both of these edges to wake up the device from stand-by?HAL_PWR_EnableWakeupPin documentation says/** * @brief Enable the WakeUp...
I am using the HAL library on a STM32L476RG and have been having trouble getting data out of a sensor. By looking at the signal with a scope I've noticed that the write bit of the device address is not being set when I try to write to the sensor's re...
Can I use the Wfe().and create a timer that triggers a event, if so how should it be done?I have a lot of interrupts that are triggered. that disturb my sleep mode.Best regards...PS: I have to sleep every 30 ms and then wake up again
