Resolved! STM32L433RC Comparator interrupt triggering on both edges rather than just rising edge.
I have used CubeMX to configure the HAL comparator driver to trigger an interrupt on the rising edge only, however the interrupt seems to occur on both edges. I checked the EXTI registers and everything seems correct. I then thought that my voltage s...
Resolved! simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when power supply drops from 3.3V to approx 3.0V then recovers to 3.3V.
simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when VDD power supply drops from 3.3V to approx 3.0V (just above BOR level) then recovers to 3.3V.All 3 Buttons are read back as active from this point on. Has anybody experience...
SAI_DMA_ERROR while using Receive_IT()
Dear Community,i'm working on an 4 Slot SAI Interface with an STM32G4 Series MCU. The FrameSync signal is kind of slow (~2kHz) so i want to use the Receive_IT() to throw an interrupt when 4 Slots (32Bit each) has received. So after starting the ADC H...
Resolved! stmpe811 I2C address on stm32f429i-disc1
I bought a stm32f429i-disc1 board and I want to learn how to communicate to stmpe811 with I2C protocol, now I'm a little confused. According to stmpe811's data sheet, its address is 0x82 because its A0 pin is connected to ground, but board's schemati...
STM32 - FMC and 16b SDRAM but 8b bus
Grettings,Can the FMC be configured to handle a similar configuration?I have an SDRAM that has byte enable pins to the upper and lower bytes (Disable -> High Z), but no pins available to map the 16 bits. So, at the moment I'm working with half the me...
HSI
Is there any information about long term stabiliy of the internal high speed oscillator (HSI)?
STM32F767/77 controller power consumption ?
I am exploring on controller selection. And need to know how much power is consumed by STM32F7 series controllers assuming that very few peripherals are used.It will have ADC, SPI, Timers, FLASH and FRAM access.So, wanted to know how much power it wi...
Encoder mode counter division possibilities?
Now every rising and fall edge are counted which results in counter incrementing by 4. I see and have tried playing with Prescaler Division Ratio which should normally be the parameter to divide incremental number but it does not work on Encoder mode...
Resolved! Free UART on P-L496G-CELL02 board?
We are using the P-L496G-CELL02 demo board and want to connect an external device through an UART.Is there (for example USART1) accessible for external connection? Which ports are connected to the Arduino compatible interface? Is there an UART aviabl...
