Can the STM32F103 support ISO 11992?
I've been asked to modify a device that uses a STMF103 on a J1939 CAN Bus to use ISO 11992. According to Wikipedia, this protocol is "similar to SAE J1939".Does anyone have experience with this protocol? And can the STMF103 be made to support it?Th...
External SRAM access using FMC (STM32f439zi) - How to connect unused pins?
I am trying to interface a Nucleo-f439zi board with an external AS6C4008-55SIN SRAM chip through an "Arduino HAT" style board I am working on. Below is my current schematic.In the chips manual, the table below is shown for using FMC to access externa...
How to free NUCLEO STM32 board pins for FMC interface use
I want to interface a Nucleo-H743ZI2 board (MB1364E) with a memory chip using STM32's FMC.In order to do this I need to free up the following 4 pins, to be used by the morpho connector:PE1, currently yellow user LED, needed for FMC_NBL1.PD8, currentl...
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...
