Posted on January 03, 2017 at 18:47Hi there, recently I was making acustic spectrometer using STM32F4-Discover. In my project im making FFT with 'arm_math' libraries and then I need to send data to PC (with which I'll display it) via UART.After maki...
Posted on June 24, 2014 at 16:58Hello,I have a timer performing input capture on one channel. Can I set another channel OF THE SAME TIMER as an output with a frequency double of the captured input signal frequency?-------------I am not 100% clear on...
Posted on October 25, 2017 at 17:45Is there any way to determine programmatically what physical pins exist on a device? Or, somewhere within the HAL libraries where its defined?For example, the STM32F411 chip in the UFQFPN48 package only has the PC...
Posted on October 26, 2017 at 06:06 I'm looking at the STM32 provided Ethernet examples that use an RTOS and have the ethernetif_input function. The function is started as a task as below: static void low_level_init(struct netif *netif) { ...
Posted on August 15, 2017 at 05:00Hi,has anyone ever managed to send a standard CAN overload frame on an stm32?So far, I could only find error handling for incoming frames but no way to send one myself.#can #overload
Posted on October 24, 2017 at 08:53Hi, I use ST-Link V2 eumlator and STM32 ST-Link Utility SW to flash STM32F103VE. At the beginning, it can flash for several days. Today it can connect to device(show device information), but can't flash. It show ca...
Posted on October 25, 2017 at 20:39I am trying to establish an I2C Connection between the two boards, but the slave (being STM32F4) is not being acknowledged by the Variscite Board. Desired setup:- Variscite DART-6UL as the master- STM32F4 as the th...
Posted on October 25, 2017 at 14:10The highlighted sentence is a duplicate - see the other one above it. One of them is obviously incorrect - which one? - and shall be removed.JW
Posted on October 25, 2017 at 13:08Dear all,I am programing a STM32F429 for creating 4 PWM for inverter aplication. I managed to create these 4 PWM using TIMER1 and channel 1, channel 2, channel 1 N and channel 2 N.The inverter works pretty good usi...
Posted on October 25, 2017 at 16:32Hi,I am using STM32F103RET6 microcontroller. On my PCB, the USART1 channel is used as RS485 communication with a SN65HVD11HD transceiver. That means to transmit/receive each character, the direction pins RE, DE pi...
