Posted on June 16, 2016 at 11:36Hello. In a very specific project I have to use 2 different I2S codecs one for input and another for output. Is it possible to do it in 1 project on same CPU? The frequencies are different. And the Data type is seems ...
Posted on June 14, 2016 at 11:54Hi, i try to implement an PWM with high pulse between two CCRx reg values. E.g. TIM8: Period = 100; CCR1 = 20; CCR2 = 25; -> create one PWM Signal with pwm pin output low 0-19 pwm pin output high 20-25 pwm pin outp...
Posted on June 16, 2016 at 05:55 Howdy all! So i have purchased a generic ebay f103 with the yellow headers, you know the one. I have worked with Atmel Arm based chips before, no ASF just register access. I cannot seem to get th...
Posted on June 16, 2016 at 21:04On this chip the JTAG TDI pin is shared as a I2C pin a well. If I use this pin as I2C, does that mean I can no longer use it as a TDI pin during operation? Or does it go to AF0 state right after reset and then proceed...
Posted on June 14, 2016 at 23:11Hi!, i'm trying to recreate the C array of the file ''artofgardens-instr '' that came as example in ''audio_playback_and_record'' files, but with no luck.Does anyone knows how to do that kind of convertion? from wav...
Posted on June 15, 2016 at 15:41 Hi there, I'm working on custom board based on STM32F103 and the IDE is Keil. I will use UART2 to print some debug logs. To do this I add the fputc function to my code in order to redirect printf to...
Posted on June 16, 2016 at 14:26Hi.I am using discovery board with STM32F100; I have made a code to generate a sinusoidal waveform through pwm via lookup table method.I think I miss something in computing the output frequency of the sine wave.Here i...
Posted on June 16, 2016 at 16:43 I'm facing with a problem regarding continuous acquisition of ADC channel in STM32F I use the interrupt at the end of conversion to call a callback function to store the acquired value. The problem regards t...
Posted on June 16, 2016 at 13:17Hello EveryoneI am trying to run my code on stm32f4, with use of interrupt routines. I have an 9dof imu including mpu6050,hmc588,bmp058. So i am interfacing 3 EXTI rsubroutine to read imu and this has been successfull...
