ZBasic Forum

Further to my last post, I'm investigating why I appear to be getting discrepancies between reported and measured rpm. So I have a scope hooked up the the car, and at approx 3000 i can measure the spark fire duration at 3.7ms and the gap between sparks as 17.2ms (its a 4 cycllinder,4 stroke with 2 c...

As usual Don you saw my problem before I did. This from your rmail seems spot on:- For the ATmega devices Register.TimerSpeed1=2 yields a timer frequncy of F_CPU/8 so the timer frequency is 1.8432MHz. This frequency isn't available on the ATxmega (which runs at 29.4912MHz) because F_CPU/16 would be ...

Previously i used a zx24a to capture engine rpm using inputcapture and in testing i found i needed the following statement to get the scaling correct. register.timerspeed1= 2 I am not trying to do the same on a zx24x,= and i note the clock speed is double the zx24a the documentation lists TimerC0 as...

ah yes - i rather suspected that might happen also.

I think i need a DPDT switch, it's just fitting it in but I think i can do it.

thanks Don

Actually, i don't this will work as the voltage divider will create a drain to ground anyway.

Like the title says, can i connect my regulated lipo output to an adc pin and have it not drain the battery at all when the ZX is not powered up. At the moment I have the adc pin connected to the input to the regulator which is always in safe range, however, i now want the option to power it from 12...

that is interesting and i'll read and digest. More Alexa focussed but i might do that later also. I found this which covers a lot. https://www.makeuseof.com/tag/control-philips-hue-lights-arduino-and-motion-sensor/ i could either convert the principals to zbasic on esp8266 using the TCPClient exampl...

Should be straightforward enough as Hue bridge is a simple webserver and Hue is controlled via json commands.

Just wondered if anyone has done it ?

it's a zx40n - i don't use the vm devices any more.

twice the speed is better - i'll see how it goes

i moved to a zx40 so could address entire io port in 1 command and speed is better but borderline for what i want to achieve. i either need a tube with longer persistence or faster processor. I note the original kits where done on PICS, not sure what speed what they ran at but is the code lower leve...

Pursuing my ongoing obsession with clock projects i decided to try and recreate an oscilloscope clock that was executed so well here http://www.dutchtronix.com/ScopeClockH3-1-Enhanced.htm I was intending to use a 328n but I note that there is not an entire output port of 8 pins available (to drive a...

I've given up on the esp8266 as a platform to run code on. Still useful as a wifi module but as a precaution i always implement the ability for a zbasic cpu to reset the esp8266 if it becomes unresponsive. The only matrix display clock project running on the esp8266 calls ResetProcessor at 3am and t...

I've made a couple of project on the esp8266 but the most recent polls a POP3 server every couple of minutes and displays appropriate message on a matrix display. The matrix display part i think is ok as it runs for days on end in a clock project, and polls an NTP server once every 24 hours The addi...

thanks don - got it working in the end

thanks - i'd missed that part.

is there a way to reference the adc. It doesn't appear to have a GPIOnn designation that i can see.

The zbasic documentation doesn't say getadc isn't implemented.
