Hello, I am having some trouble with getting I2C to work.My code:void i2c_init(void) { /* Periph clock enable */ SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_GPIO | CLOCK_PERIPH_I2C2, ENABLE); // I2C2 pins GPIO_InitI2c2ClkPin4(); // SCL at DIO4 ...
Hello, I am experiencing problems with using ADC together with BLE. When I comment out BTLE_StackTick() inside main loop, the ADC reads values correctly (checked over UART). But when BTLE_StackTick() is called, ADC always returns 0.6V. What is the so...
I am using an STEVAL-IDB008V2 board which contains a BlueNRG-2 chip. I am testing out this product using Keil uVision (version 5.29.0.0), and I am running the BlueNRG-2 sensor demo code (with sleep function removed; I learned this causes problems).T...
We produced a 4 channels RS232 to 485/422 converters using a FTDI4232 and four ST485BDR. When apply the 120 Ohm load resistor, some ST485BDR send the pin 1 to low state, lighting the RX LED.When the pin 1 goes low, the RX LED remain lite. If I touch ...
Hello,since 30. January I can't use secure sockets with my SPWF01 modules. I try to connect to fcm.googleapis.com. It looks like google changed something in the authentication (maybe no more anonymous auth or something else). Does anybody else has th...
Hii, I am started to develop the USB Keyboard using the STM32F0 Series microcontroller. I was set all settings in CubeMax for USB mouse now I am change that settings in Atollic True Studio generated files for HID USB Keyboard but Not Got Success ye...
Hi!In my situation i have two boards with S2-LP (868Mhz): one for transmit data and one for recieve. The reciever is stationary located and doesn't move. The transmitter moves back and forth at a speed 1 meter/second.My question is: should i bother a...
I configure the I2C as follows:hi2c1.Instance = I2C1; hi2c1.Init.ClockSpeed = 100000; hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2; hi2c1.Init.OwnAddress1 = I2C_ADDRESS; hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT; hi2c1.Init.DualAddressMode = I2C_...
As I am doing debugging in STM32L072CZ using ST Link/V2 by STM32 ST-Link Utility software. But I getting error message as Connect Under Reset and I have tried under all mode but same error has been repeated. How can I solve this error and I also atta...
