Hello crew,Withing the more general scope of making electronic music, I am trying to build this oscillator based on a 4049 chip:I know it's crap, but it's simple, which is good for learning I have breadboarded it successfully, I'm using a 12V supply and playing with the RC values I can adjust the frequency. Yay!Now I am trying to add voltage control to the thing. I have found another schematic with an added 1M resistor at pin 3 that says to connect CV there.

From what I can find on the web, this flag should get set to 1 after the device has physically transmitted it's payload. But it isn't, I poll the FIFO_STATUS register but the flag never gets set and I know the data was sent because I have a receiver board that receives the whole packet. The manual for the device too, has very little to say about TX_EMPTY, this is the only place the field is mentioned:The flag is set right before I begin a payload transmission.

Hello Programmers,I'm quiet frustrated now as I'm unable to figure out how I use the XGZP6847A001MPGPN pressure sensor of range -750mmHg to 7500 mmHg using ATMEGA8 chip and ADC 1 channel (10bit adc). I've the setup already and able to get the readings from pressure sensor to display. But dont know how can I limit the pressure within specified range suppose 0mmhg to -130mmhg. Please help me with the formula in C embededd to use.

You need an iron powder core, usually a Micrometals #26. You need at least 1.5mH divided by the current (i.e. 1.5mH @ 1A, 150uH @10A), the more the better. Micrometals website has an inductor designer app which has a choice of 50Hz/60Hz filter applications. The iron powder inductor is quite lossy at high frequencies, so dissipates the interference as core loss instead of reflecting it around the circuit. Who still uses filament lamps?
