Trouble activating toolchain

I just purchased the license to the Pic16 toolchain. I activated the key and then downloaded and installed the Pic16 toolchain. I have already successfully programmed some of the free targets and now I want to move to a paid target. So I have the MPLab software and my PicKit4 installed and working. ...

Re: Can't get program to run

I figured it out. I found the OSCCON register. Now it all works correctly. Thanks for pointing me in the right direction.

Re: Can't get program to run

As a follow on, I changed the Flowcode clock setting to 1mHz in "Project Options" and then created some interrupts. The interrupt intervals match up with the calculated intervals in Flowcode, so I think that this confirms the internal clock is running at 1mHz and not 48Mhz. The odd thing is that the...

Re: Can't get program to run

Thanks for responding. This is is my first PIC project, so I don't really know how to do that. I copied all of the #pragma statements from the autogenerated MPLAB code into a C-Block and disabled "Write Config on Download" and it is still slow. Using a scope and toggling outputs, it looks like I am ...

Re: Can't get program to run

I am still stuck. I have gone through all of the configuration settings and something is still wrong with the clock. My LED blink time is 50x what it should be. I was able to configure the clock at 48mHz in MPLAB and verified that by defining an interrupt and checking it with a scope. I attached a t...

Re: Can't get program to run

I got it set up in MPLAB X and the MCC and can program the device with the PICKIT4. I can flash an LED and some other simple stuff. I then wanted to program it in Flowcode, so I moved over to Flowcode and set up the paths to my MPLAB compiler and the PICKIT4. As I said, it recognizes the chip and sa...

Can't get program to run

I am trying to make my first project with a PIC18F25K50. It is just a simple LED blink.

I am using a PICKIT4. The programmer sees the chip and says that programming is successful, but then nothing happens.

I attached my program and my log file.

Thanks.

Interrupts and SPI on Arduino Nano

I started writing this as a help request, but I found the solution, so I figured I would post my experience in case it might help someone else. I am using an Arduino for a simple analog servo. I sample an analog input and an analog sensor, perform a servo calculation and then send the output to an e...

Re: ESP32 Can't sample ADC inside Interrupt Macro

Thank you for the response. I will play with that approach.

Re: Chip suggestions, fast 5V compatible

I am adding a post because I figured out my interrupt problem and wanted to share in case it helps anyone else. The interrupt definition in Flowcode only supports rollover interrupts and does not have the settings for a COMPA interrupt where the timing can be adjusted to any period. I can't run my i...
