As the switch can only concur with one case, I didn't think the break; was necessary. Turns out it is! switch (readbuff[3]){ // Speed select case '1': DelayCnt = 500; break; case '2': DelayCnt = 250; break; case '3': DelayCnt = 167; break; case '4': DelayCnt = 125; break; case '5': DelayCnt = 100; b...

I have a PIC Clicker set up driving a stepper motor, it is set up for USB and it decodes the incoming commands from a PC. One of the incoming commands invokes a motor test whereby the speed and direction of the motor can be set on the PC. The decoder reads the first byte ('$') to check whether the m...

Hmm, I thought the purpose of the USB interrupt was so you didn't need to poll the USB flag?

Hi, I'm working on a coil winding machine which is controlled by software on a PC. I chose to use a PIC Clicker (18F47J53) as the USB interface and motor controller. Using the Clicker's USB interrupt demo is fine because the only thing it does is respond to USB input messages. In my case, the main()...

Hi Lana, Not sure what you mean by using a Library? I'm using the I2C library to communicate with the IMU which is the point of the original post. As far as I can tell, there is no difference (electronically) between the PIC circuit and the STM32 circuit. Therefore I'm assuming this is a software is...

Okay, this is the code in its entirety... char readbuff[64]; char writebuff[64]; char cnt; char x; char y; char I2CReadByte; char reg1; char reg2; int MSAngle; int Angle; char AngleStr[7]; char test[4]; void USB0Interrupt() iv IVT_INT_OTG_FS{ USB_Interrupt_Proc(); } void IMU_Init(){ // Initialises t...

Hi Lana,

Thanks for the suggestion but that code package is incomplete - and useless - why is it even on Libstock???

I expected better from ME.

Hi Lana, I am using the Bosch BNO055 on a breakout board from Adafruit, this has the ability to output Heading, Pitch and Roll angles from it's internal fusion algorithm. The calling function sets the register addresses (reg1 & reg2) and the Read_IMU_Data() function should retrieve the data, convert...

Hi Wolfgang, I'm running this firmware on a Clicker 2 for STM32, the two I2C pins are on PB10(SCL) and PB11(SCA), these relate to I2C channel 2. I have initialised this using the standard 100kbps bit rate as follows... void SystemInit(){ I2C2_Init(); // Initialises the I2C2 module at PB10/11 IMU_Ini...

I have been using a Bosch IMU as part of a system that I'm building, up until recently I was using a PIC but, for various reasons, I need to upgrade the system to STM32. I had no problems reading data from the IMU with the PIC but I cannot get the ARM to read the data. This is the PIC code first, th...

Your question is missing some important information, most of which could be answered if you post your code and schematic. Your RF transceiver uses standard SPI so the MikroC functions should work fine, it's just a matter of having the right connections and initialising the SPI correctly. Incidentall...

Hi Nart,

Have a look at the circuit diagram in the user manual, Vcc (5V) is supplied from the USB port.

This has been a truely enlightening thread, especially for me because I was confronted with the choice of PIC/ARM/FPGA a couple of years ago. What doesn't surprise me is that everyone puts a lot of emphasis on the quality and availability of development tools; this was a major part of our decision m...
