Re: Empty #define statement

Hi Martin

I deleted all your macros and all your code and changed the chip to a PIC, but still this error!
There is a strange thing (for me) What is this panel with Pins in your Program even I deleted all?

Re: ADC ground ref setting

Hi Jan

I'm not sure if Flowcode supports the selection for the Vref negative (ground) pin for the ADC.
You must first initialize the converter with FC and then change the bit.

Re: Bringing up a new chip 18f24k50 Having some problems.

Hi Chad

try this setting, so your PIC is running on 48Mhz and a note: there is a similar PIC 18F25k50 with more ram for the same price.

Re: Interface board for Flowcode V8 and above. Now added RTC

Hi Martin, Hi Ben Wonderful board! I used the example from the MPU9250 and connected a small demo board from the MPU9250 to the interface board and it worked right away. Now I want to connect my own hardware. I guess it's pretty easy. Is there a circuit diagram of the interface board? regards Stefan

I guess you have to set the ADC Negative Voltage Reference Configuration bit to 1.

Hi Martin

Thats a good news thanks a lot.
I have placed an order.
one more little question.
Do you know the difference between:
Embedded Interface Board I2C SPI PWM ADC DAC Servo (WIFI Slave)
Embedded Interface Board I2C SPI UART PWM ADC DAC Servo (USB Slave)

Hi Enrique Yes, after the PIC sleeps hi wake up on this place. I suspect your PIC is crashing because of the delay in the interrupt It's not a good idea to use a delay in an interrupt.

You can use the SPI in softwaremode. In this mode you can change the pin mosi and miso.
