Dear S.T., I don't need a probe, I would like to build the circuit between probe and the ADC of a DSO. Actually I use STM32F429 DISCO demo board with a modified fw for signal acquisition and visualization on two channel but the acquisition is (obviously) 5V limited.... I need something to vary...
Dear all, I'm a little bit "rusty" with signal conditioning so, with the aim to review analog design, I would like to design a signal conditioning circuit for an oscilloscope input. I've not great expectations with bandwidth (<5Mhz) but I would like to input max 400V signals DC & AC with 1MOhm...
Hello edaboard i'm going to design a HID with an fm tuner inside. I choosed the SI4705 for the fm tuner.
This tuner communicates via I2C with the MCU and silabs tells me that "it is better to add C-R-C type filter on communication path, such as I2C_CLK,I2C_DATA"
I suppose this filter is...
Can someone explain me in a simple way why when i keep in hand the remote contol i get 5 less dbuV than leaving it on a wooden table? How can i avoid this phenomenon?
I also noticed that sometimes if i tune the antenna without keeping the remote control in my hand, the tune isn't the correct...
Thank you very much for your reply, actually I'm far below the -8dBuV (respect Lambda/4). The wire antenna 170mm long measured 75dBuV on the s.a. @ 10meters of distance, the loop antenna at the same distance measured 57dBuV on the s.a... I think can improve the antenna a little bit more...
Hello edaboarders, I'm trying to tune a pcb loop-antenna for a remote control working @ 433.92 Mhz. I didn't design the rf module i buyed it on ebay but it needs external antenna design.
I copied the antenna filter topology from an old remote control and it looks like the one shown in the...
Dear Sirs, i would like to know if Texas Instruments allows firmware copy protection with option byte or if there is a way to protect the mcu (msp430g2332) from firmware reading.
If it can help I'm using CCS (not IAR)
thank you in advance
best regards
B.M
Hello everybody, i'm trying to do program a board equipped with msp430g2332 using a MSP-FET430UIF (V1.4a) but either using IAR either using CCS i get the message error:
Fatal error (could not find the device or device not supported)... (IAR)
I checked and re-checked all connections and read...
hello folks, I need to design a NiMh battery charger (AAA or AA - 2 cells), external supply powered @ 5V, that will be used in a professional product. I don't have much experience in designing stilo battery charger and i would like to know if anyone can link some schematic / application notes...
Hello everybody, i have a problem with altium designer summer 08. When deleting the footprint of a component and going to menu Tools -> Update parameters from database (my database has a column for the footprint of the components) the footprint of the component doesn't update anymore (previously...
