Re: New Project interrupt timer slow

Hi Some of the chips can be quite frightening in their configuration, many times I've overlooked something simple :) The one second flasher test really is your best friend when working with a new chip, but unfortunately often forgotten, and the WiKi is a helpful resource for most components / featur...

Re: itag bluetooth

Hi I don''t think that it's a case of no ideas, more that the FC ESP32 BT component doesn't support your request. As you state above, you need to read the RSI and this isn't a feature of the component. I'm no ESP32 expert, only having basic working knowledge, and I'm sure it could be done if you per...

Re: New Project interrupt timer slow

Hi Heading out soon, sorry to brief. I had a very quick look at the datasheet and it appears that Timer0 can operate in either 8 or 16-bit mode. The timer can also run synchronous or asynchronous to selected source. When synchronous it is set as Fosc/4. It appears that Timer0 is set to 16-bit mode (...

Re: New Project interrupt timer slow

Hi

I don't have the datasheet for your chip to hand so can't comment on Timer0 capabilities.

However you could use Timer2 set for Internal Clock (Fosc) with prescaler set at 1:16 and rollover to 250 to give you a 1KHz interrupt. Test in hardware though.

Re: File from flowcode 4 to open with v9

Hi Following on from the above posts, I think you would be better off recreating your chart in v10 and perhaps also consider using the HX711 component instead of reading the ADC. Much easier in my opinion and examples of using the component (including calibration) can be found in the wiki https://ww...

Hi

The old forum has this post which if you scroll down you get a link to Microchip AN930, which may be helpful.

Re: Timer problems PIC18LF14K50

Hi As mentioned I don't have the chip but I do have other PICs that offer the same functionality. Using a PIC16F1939 in an BL0080 multiprogrammer (coz it was already in it) using an 8MHz clock, I set up a very basic chart with an LCD didplay and an interrupt on Timer 0 set to CLK0 with a prescale of...

Chipfryer. Many thanks for confirming what I get on my scope too. J. I'm always cautious it is something dumb on my end!

Won't say how long it took me to remember to push the Pico button before inserting lead into PC.... :lol:
