Re: Help with SPI component

Hello,
PIC16F18877 is probably not the only one to have problem on SPI harware channel.
I had the same issue with PIC16LF26K80 communicating with an SPI display gLCD_SSD1331: on Channel 1 it didn't work but on Software was ok.
Could it be a common problem?

Re: I2C versus SDI Diplays.

Hello,
i would just somebody to confirm if I2C displays take so much amount of RAM or it's just a specific component issue.

Thanks

I2C versus SDI Diplays.

Hello body, in the past I've uded some I2C display (SH1106, SSD1306) with PIC18LF26K80 and no problem seen. Now I'm trying to use the same I2C display but with PIC16F1455 or 16F1825 and in both cases, even the simple "ClearDisplay" flowchart is giving compiler error (FC7 v7.3.0.7): ClearDi...

Re: FC7 Compiler XC8 Ver 1.41 to XC8 Ver 1.45

Hello Dave,
when you select the version 1.45 in the "Project Options" I guess you pick up the wrong file. It should point to xc8.exe.
In your log I see "Uninstall-xc8-v1.45.exe".

Re: OLED Color SSD1331 display.

Hello Benj, The SDA pin should be connected to the MOSI pin and not to the MISO pin. The MISO in the display is connected to PORTC.4 in the PIC which is SDA. We may have to specify that the PIC is Master ans Display is Slave. The display has pins: GND, VCC, SCL, SDA, RES, DC, CS and there is no MISO...

Re: PIC18F26K40 I2C LCD not working

Hello, I've used 18LF26K80 with SH1106 display on I2C CH1 and it works. I cannot say anything regarding xxK40 devices however I remember I had to play with Baud speed for I2C comms and the chip speed. In my case I enabled the internal PLL to run the PIC at 64MHz and the I2C baud speed at 400KHz. Wha...

Re: GLCD NOT WORK

Hello,
I tested my configuration with external xtal 20MHz on and also the version from Celebrium but in all cases I got same results.
I give up here as this display is not very interesting for me because it takes many pins from PIC.
