    Injection current of ADC input pin

    Hy LlausST,i used R5F10BGGLFB QFP48 but it is not specified on datasheet.I find a datasheet from costumer but not specified there. Name of document: Customer Notification RL78/F13 Family 16-bit Single-Chip Microcontroller Customer Specification for Continental Injected Current Specification.It...

    Injection current of ADC input pin

    Heloo all, I have a question regardless of injection current into analog MCU pin. From datasheet maximum injection current into pin is 2mA.From my worst case calculation result a injection current ~250uA in that pin from 400ms time.On datasheet i found one expresion to calculate if this current...

    PSPICE HALL simulation

    Hy,i need your help please! I need to simulate in PSPICE an IC MLX92212, it's Latch Hall.I need to simulate response,Trise,Tfall,slew_rate but i don't find any model for this and i don't know how to simulate the DC motor on magnetic field to see the output of Hall.I don't know how to simulated...

    DC-DC Boost converter Enter in DCM mode

    Hy,I increased inductor value,frequency for 1Mhz but still nothink. I put a series led of aoutput feedback and still work,and i make some ajusted value on inductor and capacitor but i don t think if with that led will work in real life...what you think?

    DC-DC Boost converter Enter in DCM mode

    Hy I have a problem with a DC Boost converter.I want to use them on a alimentation module for constant current for optic bloc that used LED technologie,Headlights with LED technology.Input voltage will be between 12V and 24V and output between 30V and maxim 36V with 900mA current consumption.In...

    2_Channel Half Bridge Gate Driver Charge Pump

    Hy,cand someoane explain me what is the role of transistor Q1 and how that circuits work?I try to understand but i can't.Voltage VS is the power supply of a Internal Charge pump of IC. Out "CP"is out Charge pump who is a Periodic waveform.From datasheet if VBAT is grater than 13.5V then "Vcp" is...

    LCD and pic not comunication

    Thx you all for your Help!You are a great man!!The last my problem is why the LCD behave like i show in the pics?And my curiosity is wy it's work after i flash the PIC with .hex after i disconnect the LCD from the PIC.On a shield,or project,or other platform where the LCD is connected on PCB...

    LCD and pic not comunication

    Hy Okada,hy all,i try Okada code and first time was the same result.After that i connect LCD and PIC at the same VDD and VSS.And first time i power the PIC and reflash,and than i open the LCD bot still nothing.Finnaly i remove PIC cnnection from LCD and judt reflash him lonly,separate from...

    LCD and pic not comunication

    Ok,thx you verry much.I will do that soon i reache home and i will tell you the behavior.I hope that would be the problem.Thx you verry much! - - - Updated - - - I make this experiment:I make a program with arduino and arduino LCD shield and send "Hello" on LCD.It's works only if i used the...

    LCD and pic not comunication

    I ipload miKroC program above.Thx you verry much Okada.I don't know why is not worked:((.I used 4 MHZ quartz oscilator with 22pF capacitor.I put on decoupling cap between VDD and VSS with 100nF and still nothing:(

    LCD and pic not comunication

    I try anithing you say and nothing:(.I don't know what to do :((.Why is not working?What i doing wrong:(.Can anyone send me a good schematic and a good code from this pic in who from him is worked?Plese,i don't know why is not worked!From a month i still try and nothing:(

    LCD and pic not comunication

    If i reset PIC from MCLR nothing happend with LCD :(.What should be happened?If i adjust the contrast of LCD i see the pixels.I make the connection from LCD to PIC like in proteus schematics directly and i check this with a multimeter continuity and averything wa OK :( - - - Updated - - - No...

    LCD and pic not comunication

    Hy can anyone help me?Please!!I try another display,i try with another PIC and is the same.No see nothing on display,just lights :((.I don't what to do!What i'm doing wrong?Can anybode help me!!
