hcs08 + spi
Hi,
I am using Freescale's HCS08 core based controller to interface a peripheral, which has 16 bit SPI module. How can I configure the Microcontroller to communicate to the 16 bit slave
Thanks,
Joby
usb ready embedded system
Hello,
there are chips available which converts USB to UART/ SPI for USB device side.
**broken link removed**
But i have no idea of such chips in the Host side.
Hello,
The circuit in the charger monitors the charging current / voltage level across the battery. Once the battery is fully charged, the charging current will be very less or even zero and the voltage across the battery will be max. An ADC can be used to measure the analog input and interfaced...

Hello,
You need to implement a USB host in your embedded system. there are microcontrollers available with built in USB host. Also you can try out external usb chips such as ISP 1161.
rs485 connect 8051
modbus can work as single master multi- slave network. If you want to send the same data to all the slaves from the master, then you can use the broadcast mode in the modbus protocol.

Hello,
You can use 8051 also in the place of TI controller. Check the specification of the TI controller pins and find out the equailent pins from 8051. If the specs are matching then u can just replace the controller. You may find an 8051 variant with inbuilt ADC. Actually the TI...
Hello fzanbas,
Its good that you have your own idea for your project. You told that the purpose is to warm up the engine. Is it really required for the modern cars to warm up the engine before drive? I am not fully convinced with your idea. I suggest you to have a search on internet about your...
Hello,
Since the RS485 is a differential line, it can only send/ receive data at a time (Half duplex). So when you use 75176 or MAX 485 you have to use a port pin to select the transmit/ receive pin in addition to Tx and Rx.
Connections:
Tx - D
RX - R
Selection Pin - Short the DE and RE pin...
Hello,
Better you can use a system similar to the Remote Car Door Opener. Find some info about How Remote Entry Works below.

Hope it might be useful

The data send/ receive in a mobile is controlled by the firmware/ OS of the device. As we don't have access to those softwares how can we send our data? and even if u send some commands how the PIC understand the data (Communication Protocol) send by the phone? If u have some idea please share...
OK. How do you transmit the infrared from your mobile phone? If you want to use infrared then better you should make your on transmitter which can transmitt infrared signals.
smoke sensor
Hello,
Please have a look at the below link..

In the case of smoke detector, the design of casing and placing of the sensors inside the chamber will be complicated than the electronic circuitry for a better performance.
microcontroller rs485
Hi,
Use a MAX485 to interface your microcontroller to the modbus. your application is not clear. if there are only one energy meter has to be connected to the controller then you need not implement the complete modbus protocol. Modbus is mainly used to communicate in a...
8051 flash memory
for programming the flash you need an Integrated development environemnt (IDE) where you can create/ edit / compile your code in assembly or C. Then you need a programmer and the driver software to flash the program to the microcontroller.
There are many IDEs such as Kiel or...
