CMX Systems offers its RTOSes, two TCP/IP stacks, five Flash File Systems, USB Host and Device software for STMicroelectronics’ STM32 Cortex-M3 and Cortex-M4 microcontrollers. Many compiler tool chains are supported including IAR, KEIL, GNU, Raisonance, Rowley and others.
CMX-RTX is a truly preemptive, multi-tasking RTOS offering one of the smallest footprints, fastest context switching and lowest interrupt latency times available on the market today. RTOS functionality provided in CMX-RTX includes: task, message, queue, system, event, memory, resource, semaphore, and timer management. CMX-RTX includes an intuitive Windows GUI that simplifies RTOS configuration.
CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all processors and features an extremely small Flash requirement and minimal RAM requirements of about 500 bytes plus buffers for packets. The base CMX-MicroNet software package includes UDP, TCP, IP, Modem, SLIP, ICMP Echo, IGMP, and Virtual File system. Add-On Options available are: SSL/TLS, HTTP Web Server, DNS Client, FTP, SMTP, SNMP, DHCP Client, TFTP Client, SNTP, Fragmentation, POP3, PPP, CHAP, Telnet, Ethernet (ARP, BOOTP) and Wireless.
CMX TCP/IP is a full-featured, 100% RFC compliant, TCP/IP stack targeted at 16- and 32-bit processors and provides virtually all of the protocols, link layers, interfaces, and device drivers required for most networking applications. The basic CMX TCP/IP stack provides: UDP, TCP, IP, ICMP, IGMP, DNS, ARP, SLIP, Ethernet, an RTOS porting layer, a Standard BSD socket interface and a High Performance Socket Interface. Add on options include: DHCP, IMAP4, FTP, NAT, POP3, PPP, PPPoE, SMTP, SNMP, Telnet Server, TFTP/BOOTP, Web Server, SSL/TLS and Wireless.
The CMX-USB device stack offers a wide selection of Add-On options including an HID class implementation supporting Human Interface Devices such as a keyboard, mouse or joystick, a full USB Mass Storage Class with optimized drivers for accessing MMC/SD cards or other media, a CDC class supporting standard communications ports, Media Transfer Class for portable media devices, Pictbridge Extension for MTP Class, RNDIS for Remote Networking, ECM for Ethernet Networking Control, Audio, MIDI, Printer, Personal Healthcare Class and a Bootloader.
CMX-USB Host stacks (OHCI, EHCI and Proprietary) are designed for processors with both integrated USB host controllers and external USB host controllers. The CMX-USB Host package offers a FAT compatible Mass Storage Class driver which allows attachment to media including pen drives, SD/SDHC cards, NOR, NAND Flash and more. Additional USB Class options include CDC, HID, Audio, MIDI, FTDI, Hub, OBEX, ECM, EEM, RNDIS, MTP, Printer and a Bootloader.
CMX-USB Host and Device Mass Storage is fully compatible with CMX-FFS-THIN, CMX-FFS-FAT, and CMX-FFS-SAFE-FAT File Systems.
CMX offers a variety of Flash File Systems including; CMX-FFS-FAT, a FAT 12/16/32 compatible file system supporting standard media; CMX-FFS-SAFE-FAT, a FAT compatible file system with protection against unexpected resets; CMX-FFS-THIN, a scalable, reduced footprint FAT file system designed for processors with limited resources; CMX-FFS, a 100% Failsafe flash file system and CMX-FFS-TINY, a limited resource failsafe file system for Serial Flash, DataFlash and Small Sector Byte Writeable flash. CMX TCP/IP stacks, USB stacks and file systems can operate with or without an RTOS.
