| Wow. Thanks for that incredibly full answer. Setting that bit-flag worked straight away! Parity is now restored.
Also, it was the PIC16F690. Dyslexic fingers said it was a 960. Thanks again! |

| Compiler: v4.121
PIC: 16F1960 Hi. My code is doing something a little unexpected and I'm hoping you can clear up why. My device has to be able to support RS232 with and without parity. At the s ... |

| Hi guys. I'm hoping to use you as a sounding board if that's ok...
I've been working on a rather large code base which spans several products. All compiled with the CCS compiler. I'm looking at ... |

| Sadly I've been asked to write code for an existing product. The old version of this product used i2c and rs232 to do the same job. This has been written in assembler and works fine, however I've been ... | |

Forum: General CCS C Discussion Posted: Tue Oct 07, 2014 9:29 am Subject: Using SPI and Asynchronous UART simultaneously |
| Perhaps simultaneously gave the wrong impression. The device I'm working on is a serial buffer which is communicated via SPI. The hope is RS232 data is buffered coming in, and sent back over SPI; and ... | |

| Good afternoon. Quick question....
On a PIC such as the PIC16F690 which contains only the 1 EUSART, is it possible to write code using CCS to operate the uC both as an interrupt driven SPI Slave an ... |

Forum: General CCS C Discussion Posted: Thu Sep 18, 2014 7:19 am Subject: Unexpected SPI behaviour |
| Running the SPI pretty slow, 125kbps.
And yeah, a newer PIC with DMA would be amazing, but only the PIC16's we use have any heritage in space so it's what we're stuck using! I'm going to see how ... |

Forum: General CCS C Discussion Posted: Thu Sep 18, 2014 5:39 am Subject: Unexpected SPI behaviour |
| After reading through the documentation again I can see that my hunch about buffering is probably the problem. So. Is there a better way for me to be handling my SPI transactions, other than enforcing ... | |

| Hi. I'm having an awkward problem with SPI on a PIC16F1947. Explaining is going to be tricky so please bear with me. I'm using v4.121 of the CCS compiler.
The code below is designed to do the follo ... |

| Hi. Problem as in title.
Bellow is the code I'm using to test out the uart on the PIC16F690. It's designed to send back via the UART the number of times the interrupt INT_RDA has fired and the last ... |
